What is sonnenFlat?

Get $0 electricity bills with sonnenFlat! Being officially launched 5th July 2017 in Sydney, Australia, sonnenFlat enables homeowners who have an appropriately sized solar system and battery to get $0 electricity bills!

Depending on the size of your solar system and sonnenBatterie Eco 8 (must be Eco 8 model), you get a set amount of free electricity per year! Meaning if you don’t go over that amount of electricity per year, you don’t pay a cent for your electricity bill!

sonnenFlat is the way that Aussie homeowners will be able to take back the power from the energy retailers who continue to increase prices year after year and soon, paying for electricity will be like having a mobile phone plan, with the monthly administration costs of the deal being only $30, $40 or $50 per month. Imagine paying only $360 a year for power! With sonnenFlat, that’s possible.

An Example: The Wilson Family based in Sydney:

The Wilsons annual household consumption is 10,000kWh. The Wilsons currently pay $0.31372/kWh (incl.GST) which leaves them with an electricity bill of $3,472 including daily supply charges.

The solar system of 7.5kWp and the sonnenBatterie eco 8.10 (10kWh, 8th Generation battery) enable them to participate in the sonnenFlat 10 tier which leaves them with a significantly reduced energy bill, as per the calculation below.

How does sonnenFlat work?

So what’s the catch? In exchange for sonnen basically paying your electricity bills for you, you give sonnen access to your battery for helping with grid stabilisation services. For example, if there’s lots of power being exported into the grid from solar systems around the area, grid operators (not retailers) can at the click of a button, push some of that excess power into customers partaking in sonnenFlat whose batteries have spare capacity.

Looking at the Germany model for sonnenFlat, it works on a number of tiers, where the owners size of the solar system and the size of their battery energy storage determines the amount of free electricity the owner is entitled to. If a customer exceeds the amount based on their tier, then the owner starts to get charged only for electricity imported from the grid (not from power generated from your solar system and power utilised from your battery) at a rate significantly lower than standard retail electricity rates.

sonnenFlat Packages

Natural Solar is selling packages to enable owners to be eligible for a sonnenFlat Tier and are selling all sizes of the sonnenBatterie, both with and without solar panels. Whatever your needs, we can supply it and install it!

For those who do not already have a solar system, getting it installed at the same time as your battery is both a cost effective and efficient way of getting your system up and running at the lowest cost (bundle pricing, one installation team, etc.).

For those that do already have a solar system, you will get the most out of your system when you are able to take part in the sonnenFlat system, so if you already have an appropriately sized solar system, fantastic! If you don’t, we can add additional solar panels or replace your current panels with much more efficient panels.
